This table is suppose to make it easier. You need to know your Gross Lift Off Weight (GLOW) and your motor(s) specifications. Start from the top left of the table and keep going down and right until you meet all the requirements. The last cell will tell you what you have to do to fly your rocket.
| Rocket Weight GLOW | Single motor | Multi Motor | Average Thrust | Restriction |
| <453g/1lbs | <62.5g Typical G motor | <113g | <80N | Standard |
| <1500g/3.3lbs | <125g Typical H motor | <125g | <80N | Notice |

Standard = Permission of the land owner, Insurance, Fire
Permit.
Notice = Standard plus a notice called into the local FAA controller
and a CA Pyro Technician Class III Rocketry.
Waiver = Standard plus a waiver filed with the local FAA controller
and a CA Pyro Technician Class III Rocketry.
Pyro III is required when: a rocket that (1) is propelled
by one or more high power rocket motors (more than 160 Newton-seconds (36
lb.-seconds)
of total impulse or an average thrust greater than 80 N (18 lbs) or more than
62.5 g (2.2 oz) of propellant,) ; (2) is propelled by a combination of model
rocket motors having an installed total impulse of more than 320 N-sec (71.9
lb-sec); (3) is propelled by a combination of model rocket motors having
more
than a total of 125 g (4.4 oz) of propellant weight; or (4) weighs more than
1500 g (53 oz - 3.3lbs) with motor(s) installed.
